I just recently bought an 08 m3 e90 and when I lock/unlock my car it doesn\'t make the beep. I went into the settings on my iDrive and there is no option to turn them on/off while it says there is the option in the manual. Does that come with a specific package? Or am I just dumb and missed it? Its not a big deal, I was just curious. Also, if it doesnt beep does that mean the alarm isnt activated? Any help would be awesome, I\'m new to the BMW family.
